Injection Nozzles: Notes
- Loosen line unions on each injection nozzle, one at a time with engine running at fast idle. If engine speed remains constant with line removed, that nozzle is defective.
- To remove nozzle, detach injector line after cleaning connection. Plug all openings to keep dirt out of fuel system. Remove injector using Tool (8.0149). Label each injector according to its mating cylinder.
CAUTION:
Do not expose hands to injector spray during testing, as working pressure will cause fuel oil to penetrate the skin.
